The world is mobile. People, information and cultures are migrating at an unstoppable flow. Cultural affinities are shifting. At the end of the day what defines us as a part of a culture is not our geography, but our affinities. We believe that a social network is a tool to bring together a Diaspora, and unleashing the power of its talented, globalized members, and channel that energy towards the common advantage of one’s tribe. The Star Tracker is such a network, since November last year. It already has 19.000 Portuguese tribe members on board, including the President of the Portuguese Republic.
